Rene is going to the lake to visit some friends. if the lake is 60 miles away and renee is driving at 40 miles per hour the entire time. how long will it take her to get to the lake

Is known :

The distance of the lake is = 60 miles

Renee's speed is 40 mph

Asked: Time needed to reach the lake?

Settlement:

Travel time = distance: Speed

Travel time = 60 miles: 40 mph

Travel time = 1.5 hours

So Renee takes 1.5 hours to get to the Lake.

Measuring the distance, travel time, and average speed of our motorized vehicles can be done with the physics formula kinematics, which is the formula to measure irregular straight motion. Here is the review.

Kinematics is a branch of physics that studies motion by ignoring the causes of motion. Regarding the causes of motion will be discussed in Dynamics.

The motion discussed in this section is the motion experienced by an object on a straight-line path (call it a highway)

Irregular straight motion means that this movement has a fixed speed indicator for objects, Fixed means that it does not change (from the beginning to the end of the object's speed does not change) and in this case, we modify it as the average speed of the vehicle.

Regular Straight Motion is a straight motion that has a constant speed. Then the acceleration value is a = 0. Irregular linear motion is linear and the velocity value is the result of the distance with the time taken.

Speed ​​has broad meaning, which shows a change from one moment to another. And in everyday life, speed is closely related to the distance and time needed to travel, such as the way of cars, trains, rockets, bullets, and others. The international unit of speed is m / s

Distance is a number that shows how far an object changes position. The International Unit of Distance is metered (m).

Time is the interval between two states/events, or it can be the length of time an event lasts. The unit of time of the second or second (s).

Speed ​​and Time Speed ​​Formulas

Speed ​​Formula

The way to calculate speed is the distance traveled divided by travel time.

v = s / t

Distance formula

The way to calculate distance is the speed multiplied by the travel time.

s = v x t

Time formula

The way to calculate travel time is the distance traveled divided by speed.

t = s / v

Formula Description:

s = Distance traveled (m, km)

t = Travel time (hours, seconds)

v = Speed ​​(mph)

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
